| # On macOS, system python binaries like /usr/bin/python and $(xcrun -f python3) |
| # are shims. They do some light validation work and then spawn the "real" python |
| # binary. Find the "real" python by asking dyld -- sys.executable reports the |
| # wrong thing more often than not. This is also useful when we're running under |
| # a Homebrew python3 binary, which also appears to be some kind of shim. |
